About this Add-on

No configuration required, the extension is immediately active after installation. Web pages will no longer be able to listen to copy, paste and cut events to learn what you are copying or pasting, they won't even know that you do it at all. And they won't be able to interfere to push unwanted content to your clipboard when you copy text.

There are legitimate uses for these events (online editors) but these are irrelevant for most people. It is unlikely that you will ever notice the functionality loss.
